Hollow fuckable butt plugs ..who has used?

Just looking at some of these hollow butt plugs. Lots of ones for piss play and fingerl insertion etc but others are supposed to be fuckable.

The largest diameter hole in them seems to be 1.5 inches. Who has used them? will such a hole size expand and take a decent size cock? And do they stay in place while yoy are being fucked?

What is the best material... silicone? with ribs? Nice sensation? Any advice as to the best type or brand?
